2D nearfield imaging of cells with high broadband spintronic THz emitters — •Tristan Winkel, Finn-Frederik Stiewe, Doreen Biedenweg, Oliver Otto, and Markus Münzenberg — Universität Greifswald, Greifswald, Deutschland

Gaining information about cells is very important in many fields of science such as biology and medicine. 2D nearfield imaging of cells with high broadband spintronic THz emitters provides effective means to gain information about the cells. Since measurements are made with broadband teraherz pulses, the absorption spectrum can also be determined for each spatial measurement point. The spatial resolution can reach 5µm with our setup[1]. Among other things, this allows conclusions to be drawn about the water content of the cell. Our technical approach offers great potential for medical applications due to the high gain of information.
